Thanks for the compliments. Today, everybody is hunting behind the best, sharpest high speed cameras and lenses. This all is not very important, it is still the person's eye behind the camera, and not the high-end-tec quality most expensive prestige photo equipment! I don't waste my money anymore, into this pixel peeping races! I have all the HQ gear I need!
I could tell that to have latest (most advanced) version of lens and not to make beautiful photos, it isn't a gift. But to use older (previous) version of lens and to make amazing photography, it is an art :)
